for ( ; NLMSG_OK(nh, len); nh = NLMSG_NEXT(nh, len)) {
if (nh->nlmsg_type == RTM_NEWLINK) {
cb(ctx, index, info->ifi_flags & IFF_RUNNING ? 1 : 0, device);
}
}
One rtnl msg may have multi messages with nh->nlmsg_type == RTM_NEWLINK, which
will call back port_link_status() multi times. So we could not let
rtnl_link_status() return EV_ value.
